Yes this seems to be a common problem with Jeep Lyberty. The car shuts down and the rpm neeedle goes crazy. For those who replace things like gas caps and do work on valves remember nothing mechanical is going to cause the rpm needle to go crazy. It has to be in the electrical system. Good Year took advantage of me and did a lot of work on my Jeep and after $600 in repairs, the problem is still there. They wanted to charge another $800 to change the computer and I just took the car back home and am looking to see if I can get a different opinion. If anyone has a solution for this problem and has gone through this please let me know. my email is firstname.lastname@example.org<quoted text>
I sent you an email with detail. I am having the same problem and my car actually shut off the other day after the engine light started blinking. the dealer is working with me on the problem. It appears to be a valve problem, not rotating and causing build up of dirt, etc. I have a power train warranty for 100,000 miles and I am at 95,000 on my 2002 Jeep Liberty. So, I would have the dealer check that.
Thanks and good luck.
